Mathematics 1 Deneme Sınavı Sorusu #1211804

Given that a < b < c and all a, b, and c are real numbers, which of the following equals to the expression |b - a| + |a - c| ?

b + c

-2a +b + c

a + c

2a - b + c

b - c

Yanıt Açıklaması:

From the definition of the absolute value |b – a| = b – a since a < b and |a – c| = c - a since a < c. Therefore |b – a| + |a – c| = b – a + c – a = -2a + b + c.
